The Europeanisation of their football and players leaving for Europe so early in this commercial internet era seems to have really fucked them. Where is the Brazilian flair? They play more like a European team now. Even their best player Vini - he's very talented but he's nowhere near a Neymar from the previous generation in terms of technique and flair.
I am not as abreast of them as I used to be, but we will have to see if their young players coming through have that invention or of it will be coached out of them in European tactical systems.
I'd be amazed if they win the next World Cup tbh, even if it is in the Americas.
